= 1 Stop and Set-output at End of Plastication Profile
Module checks the state of this pause bit at completion of Plastication Profile to determine what further action to take:
if:

then the module:

SET

sets its outputs to PLC33 - PLC40

RESET, SYS15-B15 = 1,

immediately begins the Post-decompression Movement

and PSC05 > 00000

RESET, SYS15-B15 = 1,

sets its outputs to PSC33 - PSC40

and PRC05 = 00000

RESET and SYS15-B12 = 0

sets its outputs to zero and latches SYS13-B10
